The Swon Brothers will perform a back-to-school concert at the Center for the Arts on Russellville High School’s campus at 7 p.m. Friday.

The Swon Brothers are a country-music duo from Muskogee, Okla., made up of brothers Zach, 28, and Colton, 25.

The band gained popularity when it became a top-three finalist on the fourth season of NBC’s “The Voice.” The brothers were the first duo to make it from the Top 12 live shows to the season finale.

“The show was pretty much a whirlwind experience,” Colton said of “The Voice.” “We did not expect to make it that far. We couldn’t believe we got to work with Blake [Shelton]. It was like working with a big brother. He went above and beyond.”

The brothers started performing as children with their parents’ Southern gospel group Exodus. In 1995, the brothers performed Elvis and Frank Sinatra songs in their parents’ variety show, Westwood Music Show, in Wagoner, Okla.

Zach said he hopes to see a big turnout in Russellville.

“We’re excited and can’t wait to be there,” he said. “We want everybody to come out and enjoy the show. We want people to have a great time. The more fun the audience has, the more fun we have.”
